Buyer acknowledges and understands that all such materials that have been made available by Seller are only for Buyer’s convenience in making its own examination and determination prior to the Effective Date as to whether it wishes to purchase the Property, and, in so doing, Buyer has relied exclusively upon its own independent investigation and evaluation of every aspect of the Property and not on any materials supplied by Seller.

Without limiting the generality of the foregoing, Seller has also made or shall make available, in Seller’s discretion, at Seller’s offices, on the Diligence Database, or at the Property for review and copying, at Buyer’s expense, the following due diligence items (together with the Reports, collectively, “Due Diligence Items”): (i) on or prior to the Effective Date, (a) to the extent in the possession of Seller or Seller’s property manager, any plans and specifications for the Property, (b) copies of all service contracts or service agreements relating to the maintenance and operation of the Property including, without limitation, the service contracts set forth on Exhibit “J” hereto (but expressly excluding any contracts Seller determines are “master contracts” affecting other properties in addition to the Property and which will not be assigned to Buyer at Closing) (collectively, the “Contracts”), none of which shall be assigned to or assumed by Buyer; (c) property tax bills for the last three (3) fiscal tax years and the property tax bill for the current year to the extent in the possession of Seller; (d) operating statements for the Property for the last three (3) calendar years and the current year-to-date; (e) to the extent in the possession of Seller, any existing ALTA survey; and (f) copies of the Leases; and (ii) following the Effective Date, to the extent in the possession of Seller, any other materials concerning the ownership, maintenance or operation of the Property that are reasonably requested by Buyer (but excluding any materials that Seller is prohibited by applicable contracts or law from disclosing, any attorney-client privileged materials, internal appraisals, internal correspondence, reports and memoranda and similar proprietary or confidential information, and any materials that are not directly related to the current maintenance and/or management of the Property such as, without limitation, Seller’s financial projections, forecasts, budgets and company tax records). Seller shall have no liability or responsibility with respect to the accuracy or completeness of the information and/or materials included in the Due Diligence Items. Seller acknowledges Buyer has or may discuss or otherwise inquire about matters related to the Property with various governmental entities and utilities and the other Due Diligence Items with tenants under the Leases and other third parties. In this regard, Buyer is permitted to contact all necessary third parties, and discuss with such third parties Due Diligence Items; provided, however, Seller is first given written or telephonic notice and a reasonable opportunity to be present at such contact or discussions at a time and location reasonably convenient to Seller.

Buyer hereby acknowledges and agrees that (i) Buyer has had the opportunity to review and investigate the Due Diligence Items, the physical and environmental condition of the Property, the character, quality, value and general utility of the Property, the zoning, land use, environmental and building requirements and restrictions applicable to the Property, the state of title to the Property, and any other factors or matters relevant to Buyer’s decision to purchase the Property, and (ii) Buyer has determined that the Property is acceptable to Buyer.

Prior to conducting any inspection or testing, Buyer or its testing consultants, as applicable, shall deliver to Seller a certificate of insurance naming Seller as additional insured (on a primary, noncontributing basis) evidencing commercial general liability and property damage insurance with limits of not less than Two Million Dollars ($2,000,000) in the aggregate for liability coverage and not less than One Million Dollars ($1,000,000) in the aggregate for property damage. Notwithstanding the foregoing, Buyer shall not be permitted to undertake any air sampling or any intrusive or destructive testing of the Property, including, without limitation, a “Phase II” environmental assessment (collectively, the “Intrusive Tests”), without in each instance first obtaining Seller’s prior written consent thereto, which consent Seller may give or withhold in Seller’s sole and absolute discretion. Seller, and its representatives, agents, and/or contractors shall have the right to be present during any such Intrusive Test. If Seller fails to advise Buyer of its disapproval of any proposed Intrusive Tests within such two (2) business day period, such failure shall be deemed Seller’s disapproval thereof. Buyer hereby agrees to request any and all of its vendors and consultants (a) to include a provision in its report or study that entitles Seller and its designee to rely upon such report, but only if such language is acceptable to such vendor or consultant and available at no cost to Buyer, and (b) to provide to Seller, concurrently with the delivery to Buyer, a true and complete copy of all tests, reports, studies and the like generated by such vendor in connection with Buyer’s inspection of the Property, without warranty by Buyer. Buyer hereby indemnifies and holds Seller and the Property harmless from any and all costs, loss, damages or expenses of any kind or nature arising out of or resulting from any entry and/or activities upon the Property by Buyer and/or Buyer’s consultants; provided, however, such indemnification obligation shall not be applicable to Buyer’s mere discovery of any adverse physical condition at the Property, except to the extent Buyer or its consultants aggravate such condition, or any damage caused by Seller or its agents. Buyer’s indemnification obligations under this section shall survive the Close of Escrow or any termination of this Agreement.

All amounts collected by Buyer subsequent to Closing relating to rents which are delinquent by more than thirty (30) days will be promptly remitted to Seller; provided, however, all rents received by Buyer after Closing will be applied first to the rental period in which the Closing occurred, second to any current rental period following the Closing and third to satisfy delinquent rental obligations for any period before Closing not prorated at Closing. Seller will retain all ownership rights relating to any rents which are delinquent by more than thirty (30) days; if Buyer has not collected the same within thirty (30) days from the Closing Date, then Seller may take such action as it deems necessary to collect such rents which are delinquent by more than thirty (30) days, including the commencement of an action against the tenants under the Leases or any other person liable for such delinquent rents, but not including any action for unlawful detainer or other action seeking to terminate such tenant’s occupancy of its premises. All amounts paid to Seller subsequent to Closing relating to rents which are due and owing for the period prior to Closing shall solely belong to Seller. All amounts paid to Seller subsequent to Closing relating to rents which are due and owing for the period after Closing shall belong to Buyer, provided that before turning said amounts over to Buyer, Seller shall have the right to offset against said amounts any sums otherwise due and owing to Seller pursuant to the terms of this Section 8. Notwithstanding the foregoing, if any of such operating expenses and other charges and expenses are payable by tenants under the Leases (collectively, the “Tenant Charges”) on an estimated basis, then the Tenant Charges for the period of time prior to the Closing shall be reconciled against actual charges and expenses for such period, provided that such reconciliation shall not be performed until one hundred eighty (180) days following the Closing Date (the “Reconciliation Period”). Buyer shall prepare such final reconciliation (as approved by Seller) and forward the same to Seller for Seller’s review and approval on or before the end of the Reconciliation Period. If the final reconciliation shows that Seller owes Buyer additional sums, Seller shall deliver such amount to Buyer within ten (10) days after receiving such final reconciliation from Buyer. If the final reconciliation (as approved by Seller) shows that Buyer owes Seller additional sums, Buyer shall pay such amount to Seller within ten (10) days after Buyer’s delivery of the final reconciliation to Seller. Other than as set forth above, there shall not be any further reconciliation of such Tenant Charges after the final reconciliation thereof, the proration of such Tenant Charges pursuant to the final reconciliation being conclusively presumed to be accurate. After the final reconciliation of Tenant Charges is made by and between the parties, Buyer shall be solely liable and responsible to the tenants under the Leases for such reconciliation of Tenant Charges under the Leases. Seller shall reasonably cooperate with Buyer during the Reconciliation Period regarding Tenant Charges by allowing AT&T to audit Seller’s books and records with respect to such Tenant Charges at Seller’s management office subject to the applicable terms and conditions of AT&T’s Leases. The foregoing covenants made by the parties with respect to the final reconciliation of the Tenant Charges shall survive the Closing.

8.4 Security Deposit. Buyer shall be credited and Seller shall be charged with the balance of the security deposit then held by Seller under the Leases. In the event that Seller holds any letters of credit as a tenant security deposit, then prior to the Closing Seller shall (i) execute and deliver to Escrow Holder such assignment and/or transfer documents as may be called for under such letters of credit for the transfer of such letters of credit to Buyer, and (ii) at Buyer’s option, either deliver into escrow with Escrow Holder or deliver to Buyer, upon confirmation of the Closing, the originals of such letters of credit. Buyer shall be responsible for the amount of the transfer fee required under such letters of credit.

10

8.5 Operating Expenses. All utility service charges for electricity, heat and air conditioning service, other utilities, elevator maintenance, common area maintenance, taxes other than real estate taxes such as rental taxes, other expenses incurred in operating the Property that Seller customarily pays and that are not paid by tenants on an estimated or other basis, and any other costs incurred in the ordinary course of business for the management and operation of the Property not so paid by tenants, shall be prorated on an accrual basis. Seller shall pay all such expenses that accrue prior to the Close of Escrow and Buyer shall pay all such expenses accruing on the Close of Escrow and thereafter. Seller and Buyer shall obtain billings and meter readings as of the Close of Escrow to aid in such prorations.

8.6 Leasing Costs. If the Closing occurs, (a) Seller shall be responsible and shall pay for the costs of tenant improvement work or allowances, third-party leasing commissions, legal fees and other leasing costs (collectively, the “Leasing Costs”), including those shown on Exhibit “K” attached hereto, relating to the initial term of those Leases executed as of the Effective Date, and (b) Buyer shall be responsible and shall pay for the Leasing Costs relating to or arising from (i) the exercise by any tenant, after the Effective Date, of a renewal, expansion or extension option contained in any of the Leases executed as of the Effective Date; and (ii) any New Leases, or modifications to Leases in effect as of the Effective Date, entered into after the Effective Date in accordance with the terms of Section 9.2 below. Any Leasing Costs which are the responsibility of Buyer which are paid by Seller prior to the Closing shall be reimbursed by Buyer to Seller at the Closing through escrow with Escrow Holder. If, on the Closing Date, there are any outstanding or unpaid Leasing Costs which are the responsibility of Seller as set forth herein, then on the Closing Buyer shall be entitled to a credit toward the payment of the Purchase Price at Closing in the amount of such unpaid Leasing Costs, and following the Closing Buyer shall assume and be responsible for the payment of such Leasing Costs to the extent of such credit, Seller shall assign to Buyer all construction contracts relating to such outstanding Leasing Costs, and Buyer shall indemnify and defend Seller for the failure to complete such work related to such outstanding Leasing Costs for which Buyer received a credit.

8.7 Contracts. Seller shall be responsible for all amounts due under any Contracts; it being understood that none of Seller’s obligations under any Contracts will be assumed by Buyer at Closing.

8.8 Final Adjustment. At least two (2) business days prior to the Closing Date, the parties shall agree upon all of the prorations to be made and submit a statement to Escrow Holder setting forth the same. In the event that any prorations, apportionments or computations made under this Section 8 shall require final adjustment, then the parties shall make the appropriate adjustments promptly when accurate information becomes available and either party hereto shall be entitled to an adjustment to correct the same, but in no event shall such final adjustment occur later than the end of the Reconciliation Period. Any corrected adjustment or proration shall be paid in cash to the party entitled thereto. The provisions of this Section 8 shall survive the Close of Escrow.

9. Covenants of Seller. Seller hereby covenants with Buyer, as follows:

9.1 Contracts. Seller will not enter into any new Contracts or any amendments or modifications to the existing Contracts, which new Contracts or modifications will survive Closing or otherwise affect the use, operation or enjoyment of the Property after Closing (collectively, “New Contracts”) without Buyer’s prior written consent, which consent may be withheld in Buyer’s sole discretion, and which consent will be deemed to have been given by Buyer if Buyer does not notify Seller in writing to the contrary within three (3) business days after Seller provides written notice to Buyer of such New Contract. Notwithstanding anything to the contrary herein, Seller shall be entitled to enter into any New Contracts following the Effective Date without Buyer’s prior written consent if such New Contracts are terminated by Seller prior to the Closing Date.

9.2 Leases. Seller will not enter into any new Leases or any amendments or any extensions of existing Leases for a period which will survive Closing or otherwise affect the use, operation or enjoyment of the Property after Closing (collectively, “New Leases”) without Buyer’s prior written consent, which consent may be withheld in Buyer’s sole discretion, and which consent will be deemed to have been given by Buyer if Buyer does not notify Seller in writing to the contrary within three (3) business days after Seller provides written notice to Buyer of such New Lease. Seller shall promptly deliver to Buyer any written notices received from AT&T, as tenant, after the Effective Date and until termination of this Agreement or Closing with respect to the Leases and/or the Property.

15

this Agreement, in which event (A) the Deposit and any other funds deposited by Buyer into escrow with Escrow Holder and all interest earned thereon shall be returned to Buyer, and (B) Seller shall reimburse Buyer for Buyer’s Due Diligence Expenses. Any such election shall be made by Buyer not later than five (5) business days from Buyer becoming aware of such fact, provided that any election by Buyer to terminate shall not be effective unless Seller fails to cure such changed representation or warranty within thirty (30) days following the delivery of Buyer’s termination notice. If Seller elects to cure any changed representation or warranty following a termination of this Agreement by Buyer, and the end of such 30-day cure period extends beyond the Outside Closing Date, then the Outside Closing Date shall be extended by two (2) business days following the end of such 30-day cure period.

11.15 Seller’s Knowledge. Whenever phrases such as “to Seller’s knowledge” or “Seller has no knowledge” or similar phrases are used in the foregoing representations and warranties, they will be deemed to refer exclusively to matters within the current actual (as opposed to constructive) knowledge of the Seller’s Representatives. No duty of inquiry or investigation on the part of Seller or Seller’s Representatives will be required or implied by the making of any representation or warranty which is so limited to matters within Seller’s actual knowledge, and in no event shall Seller’s Representatives have any personal liability therefor. As of the Effective Date, Seller’s Representatives are persons who have knowledge of the matters set forth in Section 11.2 – Section 11.5 and Section 11.7 – Section 11.8 compared to other persons who are part of Seller’s organization.

11.16 Survival. All of the covenants, representations and warranties of Seller set forth in this Agreement will survive Closing for a period of nine (9) months after the Closing Date. No claim for a breach of any covenant, representation or warranty of Seller will be actionable or payable if (i) Buyer does not notify Seller in writing of such breach and commence a “legal action” thereon within said nine (9) months, or (ii) the breach in question results from or is based on a condition, state of facts or other matter which was actually known to Buyer prior to Closing.
